UVC lamps come from ultraviolet light. Ultraviolet light is an invisible light wave that exists on the outside of the ultraviolet end of the spectrum, so it is called ultraviolet light. It is a kind of light wave, which is divided into four different bands: A, B, C, and D according to different wavelength ranges.
1 UVA lamps
The UVA lamp has a wavelength between 320 and 420 nm, and its center value is 365 nm. It is commonly used in industrial glues. Curing, tungsten ore identification, fluorescence detection, biopolymerization, oil pollution detection, ore exploration, criminal detective, textile industry, archaeology, health, stage, nightclub, theater and signal lighting.
2 UVB lamps
UVB lamp, wavelength 275~320nm, also known as medium wave erythema effect ultraviolet, mainly used in health, aging test, spectrum analysis, etc. UVB ultraviolet has erythema effect on the human body, can promote the metabolism of minerals and the formation of vitamin D in the body, However, prolonged or excessive exposure can tan and cause redness and peeling. Appearance disease phototherapy tubes, UV light to keep healthy, and plant growth lights are made of special transparent violet glass (no light below 254nm) and phosphors with a peak around 300nm.
3 UVC lamps
UVC lamp, wavelength 200 ~ 275nm, also known as short-wave sterilization ultraviolet. It is very close to the peak wavelength (265nm) of the bactericidal efficiency curve, so when the 253.7nm radiation reaches a certain value, it can kill enteric bacteria, Aspergillus flavus and HBsAg (hepatitis B surface antigen) and other bacteria in a relatively short time. extinguish. Ultraviolet germicidal lamps emit UVC short-wave ultraviolet rays.
